More Optics Hacks

A smartphone can perform other optical tricks. Harvest a focus lens from a laser pointer, and attach it to the phone’s camera with some wire. The lens will magnify images to make a DIY microscope (full instructions here). Or stick a few pieces of clear tape over the flash, and color them with blue and purple Sharpie markers. This filter blocks out most visible light and leaves only the ultraviolet spectrum, turning the phone’s flashlight function into a blacklight (full instructions here).
